Paint white edges

Set brush opac­ity to 30%, then paint with a large soft-edged brush around the edges to fade it out to white. In the Lay­ers panel, cre­ate a new Bright­ness Con­trast ad­just­ment layer, and set Bright­ness 24, Con­trast 21. Then add a Photo Fil­ter ad­just­ment layer – Cool­ing Fil­ter (82).
